Machine tool for simultaneously finishing a plurality of parallel surfaces

摘要

A machine tool for supporting a workpiece during the finishing of a plurality of surfaces has a pair of center support means which are coaxially aligned for rotatably supporting a shaft and gear structure. Bearing support surfaces can be simultaenously machined concentric with the axis of the center supports. A gear finishing tool is supported on another axis which is disposed in nonintersecting relation with the axis of the center supports for simultaenously machining a gear surface.
